Let me just say this....if its leaking fuel, its more than a 90% chance its sucking air. Thats the reason why when you test things for leaks, you use a regulated air source. Air will find holes that liquids wouldn't think about coming thru.
In these older trucks, if in doubt, replace it. If a fuel line in hard, replace it. If its got dry cracks in it, replace it....
If you see a dry cracked rubber brake line going to your front brakes, you'll replace it, right? Do the same for the fuel lines....
Check valve in the return line is a +.
I replace all the mechanical lift pumps I can get with quality electric pumps. A busted diaphram will pump your crankcase full of diesel. Plus when old, you loose pressure.
A electric pump will prime your filter faster pressurizing your line with the switch being turned on, plus I wire them into a Hobbs Switch. You loose oil pressure, it kills your motor...simple, safe insurance.

Have you ever seen an injector taken apart?
Good place for a check valve is about three inches BEFORE the VP inlet.

I used to work at a shop reworking pumps and injectors....25+ years....for diesel trucks and cars.
